“…This system represented an electrical elevator depends on some orders that received from the outside control pushbuttons and in the other hands the signals that received from the internal sensors which transmitted the instant change of elevator cabinet position as well as the elevator door case (open or close) these sensors depends on a mechanical action then changed it into an electrical signals that the PLC received it and starting to processing through the ladder logic program which it already saved in the PLC as an instructions to provide the output signals that will be responsible for moving the electrical motors of cabinet and door of elevator. this process will be described in the block diagram shown in Figure 1 [4].…”

<span>This paper represents the possibility of controlling an electrical elevator model using PLC and studying some parameters to ensure its work, this model have been designed and constructed to perform a completed elevator work in an automating technique according to its programming and controlling method that making the connecting much more easier and safer than real relays and complicated wiring method. As well as the small DC motor drive (gear box) electrical motor that used to drive the elevator cabinet which made the transition from floor to floor much smoother and much efficient than the traditional elevators.</span>

“…Compared with first-and second-order kinematics, jerk analysis seems less important. However, in some applications, such as servo control of motors [3], motion planning [4,5], human-robot interaction [6], elevator control [7], and design of rollercoasters [8], third-order kinematics is also needed to be considered, for it has impacts on electron device, vibration of mechanisms, and body feelings [9]. For instance, if the jerk of a robot is large during fast motions, the acceleration changes frequently and will lead to premature wear of joints or actuators.…”

Higher-order kinematics of mechanisms has been applied in servo motor control, human-robot interaction and machinery life design fields, etc. The representations of acceleration and jerk by screws have been fully developed by researchers with the methods of the differential of the matrix representation of SE(3) group. Clifford algebra, which is tighter and with higher computational efficiency than the matrix method, is another representation of the motions of rigid bodies. It has been used in position kinematics, grub task motion planning, and robot vision for its convenience of geometric representations and calculations. As far as we know, the work of higher-order kinematics of mechanisms based on Clifford algebra is rare. First, after recalling the based theory of motion representation in conformal geometric algebra (CGA), the mathematical relationships between flag and motor are built. Second, a method for the higher-order kinematics modeling of serial chain mechanisms is proposed. Finally, the higher-order kinematics of the 3-RRS parallel mechanism is built to prove the correctness of the algorithm. This work further enriches the application of CGA for the higher-order kinematics modeling of parallel mechanisms.

Gyroscopic signal smoothness assessment by geometric jolt estimation

The present contribution focuses on the estimation of the geometric acceleration and of the geometric jolt (namely, the derivative of the acceleration) of a multidimensional, structured gyroscopic signal. A gyroscopic signal encodes the instantaneous orientation of a rigid body during a full three‐dimensional rotation that is regarded as a trajectory in the curved space SO(3) of the special orthogonal matrices. The geometric acceleration and jolt associated to a gyroscopic signal are evaluated through the rules of calculus prescribed by differential geometry. Such an endeavor is motivated by recent studies on the smoothness of human body movement in biomechanical engineering, sports science, and rehabilitation neuroengineering. Two indexes of smoothness are compared, namely, a normalized proper geometric acceleration index and a normalized proper geometric jolt index. Our investigation concludes that, in the considered experiments with measured signals, for relatively low values of the acceleration and of the jolt indexes, such indexes are strongly positively correlated.
